Configuring call diversion in the FRITZ!Box

You can set up call diversions in your FRITZ!Box. Incoming calls are then automatically diverted to another line, a particular telephone, or to an answering machine. You can set up a call diversion for all incoming calls or just for particular calls.

For example, you can define that

all calls will be diverted to another line.

all calls in which the caller does not transmit a telephone number will be diverted to an answering machine.

Important:If you would like to divert anonymous calls to one of the FRITZ!Box's internal answering machines, proceed as described in this guide.

all calls from a particular person in the FRITZ!Box telephone book will be diverted to your mobile telephone.

all calls to a particular number will be diverted to another line if that number is busy.

Requirements / Restrictions

For security reasons, you cannot set up call diversions to premium-rate numbers.

With some types of call diversion, calls from "important persons" from your telephone book are forwarded as a parallel call. For example, if all calls are diverted immediately, then telephones still ring when these callers call.

Internal calls cannot be diverted.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

Important:A second connection is established (at additional cost) when a call is diverted to an external telephone number. If you have only one telephone number, it must be possible to use it for two connections at the same time. This is usually the case for Internet numbers, but never possible on analog landlines.
